[parent] Collatz tree (Data Structure)

A Collatz tree or Collatz graph is a tree representation of several Collatz sequences joined together at their common terms the closer they are to the root term, which is 1. Typically the powers of 2 are placed in the central column, though placing to the left or the right are also viable options. In the following illustration, given to a height of 12, the powers of 2 are placed in the rightmost column:

$\displaystyle \begin{xy} *!C\xybox{ \xymatrix{ 96\ar[d] & 17\ar[dr] & 104\ar[d]... ... & & 4\ar[d] \ & & & & & & & & & 2\ar[d] \ & & & & & & & & & 1 } } \end{xy}$
